MAN Energy Solutions on Wednesday (29 March) said MAN 49/60DF engine has received its Type Approval after a five-day programme on the testbed at company HQ in Augsburg, Germany. 

The Type Approval Test (TAT) was witnessed by inspectors representing the ABS, BV, CCS, DNV, LR and RINA classification societies, who signed the test protocol upon the successful completion of the schedule.

Marita Krems, Head of Four-Stroke Marine & License, MAN Energy Solutions, said: “Today marks the latest milestone in the 49/60DF’s journey since its concept release in 2018. As we enter a new era of decarbonisation, the 49/60DF is an obvious choice for vessel owners with ambitious, emission-reduction targets that prize full fuel-flexibility and multiple options for clear emission paths.”

Thomas Huchatz, Sales Manager Four-Stroke Marine, MAN Energy Solutions, said: “Over the last eighteen months, we have demonstrated the engine’s reliability and robustness. The TAT now issued is a certificate of conformity that confirms that the engine meets the regulatory, technical and safety requirements required to enter the marketplace.”

The most recent addition to its four-stroke engine portfolio, the dual-fuel engine is capable of running on LNG, diesel and HFO as well as a number of more sustainable fuels including biofuel blends and synthetic natural gas. MAN Energy Solutions states that it sets a benchmark in terms of fuel efficiency within four-stroke engines – both in gas and diesel mode – and therefore minimises fuel costs and potential costs for CO2-emission certificates.

The new 49/60DF engine platform features MAN’s latest technologies, including two-stage turbocharging, second-generation common-rail fuel injection, the SaCoS5000 automation system, and MAN’s next-generation Adaptive Combustion Control ACC 2.0 that automatically optimises combustion. The engine also retains well-proven MAN technolgies such as the gas-injection system, pilot-fuel-oil system and MAN SCR (Selective Catalytic Reduction) system.

The MAN 49/60DF can operate and even start in gas mode where it complies with IMO Tier III without exhaust gas after-treatment. In diesel mode, it complies with Tier III when combined with MAN’s SCR system.

Soot emissions in diesel mode are halved due to the second-generation common-rail system 2.2, while the 49/60DF’s methane emissions are also drastically reduced in gas mode. The engine’s benchmark efficiency and fuel-flexible design offers multiple paths to emission compliancy leading up to 2050, as per the current Fuel EU draft.

The new engine is also methanol-ready, meaning it is inherently ready for retrofit to running on methanol should the demand arise at a later stage. Conversions are straightforward as all engine variants originate from an initial, modular engine design.

MAN Energy Solutions is also introducing a pure diesel engine based on the 49/60 platform that will be methanol- and LNG-ready and features the same technology upgrades as its dual-fuel sibling; the engine can also operate on bio-fuels.

Singapore-based ONE celebrates maiden voyage of methanol-and-ammonia ready boxship

Singapore-based container shipping company Ocean Network Express (ONE) on Thursday (3 July) said it celebrated the maiden voyage of containership ONE Solidarity as the ship made its first-ever arrival in Shekou, China. 

“As one of our S-series methanol and ammonia ready container vessels, ONE Solidarity is another demonstration of ONE’s commitment to sustainable shipping,” the company said in a social media post. 

Following the successful deployment of ONE Singapore and its sister vessels, ONE Solidarity will be deployed on the Mediterranean Pacific South 2 (MS2) service. 

“Her deployment will boost our service capacity, ensuring faster, more reliable, and highly efficient shipping offerings across key global trade lanes,” the company added.

“Lucia Cosulich” enters final preparation ahead of bunkering operations

Fratelli Cosulich Marine Energy on Thursday (2 July) celebrated the delivery of Lucia Cosulich at Taizhou Maple Leaf Shipyard in China.

The vessel is the second of four sister methanol-ready IMO II bunker tankers developed within the Group’s fleet expansion programme and follows the launching ceremony held on 2 May 2026.

Designed to support the Group’s bunkering operations and future fuel requirements, Lucia Cosulich is part of the new generation of vessels developed by Fratelli Cosulich Marine Energy to combine operational reliability, safety and fuel flexibility.

Lucia Cosulich will now enter the final preparation phase ahead of its next operational steps, further strengthening the Group’s ability to provide reliable bunkering solutions.

“We wish Lucia Cosulich and her crew fair winds on the next stage of her journey,” the company said.

DNV: Alternative-fuelled vessel orders down 11.6% in H1 2026

DNV: Alternative-fuelled vessel orders down 11.6% in H1 2026

Latest data from classification society DNV’s Alternative Fuels Insight (AFI) platform showed a total of 15 new orders for alternative-fuelled vessels were placed in June 2026.

This consisted of 10 orders for LNG-fuelled vessels, nine of which were car carriers and one a CO2 carrier. The remaining five orders were for LPG/ethane carriers.

Two LNG-bunker vessels were also ordered in June, bringing the total in this segment to seven so far in 2026.

In total, 137 alternative-fuelled vessels were ordered in the first half of 2026, down 11.6% from 155 in the same period in 2025. 

Over half of these (73) were for LNG-fuelled vessels, with most coming from the container (42) and car carrier (21) segments. LPG/ethane carriers were also prominent, with 55 new orders, a significant uptick compared to the first half of 2025 (15). The remaining orders were for vessels fuelled by methanol (2), ethanol (2), ammonia (4), and hydrogen (1).

Deliveries in the first half of the year point to continued uptake of alternative-fuelled tonnage across several segments, with 61 LNG-fuelled vessels and 38 methanol-fuelled vessels delivered so far in 2026.

More recently, Exmar took delivery of what it described as the first oceangoing dual-fuel ammonia vessel, marking a step beyond earlier ammonia-fuelled deliveries, which have largely been associated with pilot or demonstration projects rather than commercial deployment.

DNV: Alternative-fuelled vessel orders down 11.6% in H1 2026

Jason Stefanatos, Global Decarbonization Director at DNV Maritime, said: “What we can take away from the first half of 2026, in terms of the alternative-fuels orderbook, is that we have a market progressing at different speeds depending on segment economics, fuel availability, and the regulatory landscape. Shipowners and other stakeholders are pursuing different pathways based on their individual priorities and requirements.

“LNG remains the leading near-term fuel option, with order activity continuing to be led by containers and car carriers. LPG and ethane carriers have also accounted for a significant share of activity in the first half of the year, while developments in areas such as ammonia and ethanol show that multiple pathways continue to be explored.”
